Aligning biscuit slots accurately can be a time consuming, fussy endeavor. While there are lots of methods out there, I haven't seen one as simple as this in a very long time. It looks like a somewhat basic workbench, but really is a dedicated jointing station complete with layout marks, a clamping bar and spring clamps. The Versidex works with most plate jointers as well as the Festool Domino. The system comes in basic, deluxe, and premier configurations that range in price from about $3200 to $7500.
